622 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



Gen. Plexippus, Koch. 

 Plexippus adansonii. 



Attus adansonii, Sav. et Aud. Egypte, p. 169, pi. vii. fig. 8. 



At/us tardigradus, id. ibid. p. I/O, pi. vii. fig. 13. 



Attus oraniensis, Luc. Explor. Alger, p. 144, pi. v. fig. 8. 



Attus nigrofuscus, Vins. Aran, des iles de la Reunion, Maurice et 

 Madagascar, 1863, p. 59 et 302, pi. x. fig. 8. 



Three adult males and an adult female were found at Cairo. 



I feel no hesitation in determining the Attus nigrofuscus, Vinson, 

 to be of this species. Savigny and Lucas figured only the males, 

 while Vinson describes and figures the female alone. Numerous ex- 

 amples of both sexes received from Bombay and Ceylon agree exactly 

 with the examples found both in Egypt and Palestine ; nor can I find 

 any difference in examples lately received from Edward Newton, Esq., 

 from the Mauritius. 



Gen. Menemerus, Sim. 

 Menemerus vigoratus. 



Euophrys vigoratus, Koch, Die Arachn. xiv. p. 14, figs. 1282, 1283. 

 A single example of the female (immature), determined by 

 M. Simon to be of this species, was found near Cairo. 



Menemerus heydenii. 



Menemerus heydenii, Sim. Monogr. des Att. d'Europe, Ann. Soc. 

 Ent. Fr. 1868, 4 e ser. viii. p. 665. 



Adult and immature examples of both sexes were found not un- 

 frequently upon the trunks of palm trees near Cairo and in Upper 

 Egypt. 



Menemerus animatus, sp. n. (Plate LX. fig. 89) 



Adult male, length 2g lines. 



The cephalothorax is of a rather flattened form ; its colour is dark- 

 brown, with a broad yellowish marginal band, a large, somewhat sub- 

 triangular patch on the thorax (continued down the hinder slope in 

 a narrow band) of the same colour, and a small spot behind each 

 posterior eye, densely clothed with white depressed hairs, with which 

 also the ocular area and the clypeus are more or less clothed ; brown 

 and golden-yellowish hairs are also often intermixed with the others 

 on the ocular area. 



The eyes are in the ordinary position ; the ocular area appears to 

 be about equal in length and breadth ; the length, however, of the 

 anterior row exceeds slightly that of the posterior one ; and the 

 eyes of the intermediate row are rather nearer to the posterior than 

 to the anterior one. 



The legs are moderate in length and strength ; they do not differ 

 greatly in their length, which appears to be relatively 4, 1, 3, 2 ; 

 their colour is yellow ; and they are furnished sparingly with hairs, 

 slender bristles, and spines, each tarsus terminating with a small 

 dark-coloured scopula beneath the tarsal claws.
